Introduction: Dietary calcium and phosphorus appear to be important determinants of dyslipidemia and hypertension. We have investigated (1) the prevalence of hypocalcemia and hypophosphatemia in an Iranian population, and (2) the association between nutrient's intake and serum levels of calcium and phosphorus. Methods: A total of 908 individuals were enrolled using a stratified-cluster sampling method from the Mashhad stroke and heart atherosclerosis disorder (MASHHAD) study. Dietplan6 software was used for 24-hour recalls and food frequency questionnaire to investigate macro- and micronutrient intakes of our population, followed by univariate analysis for evaluation of the association of dairy consumption with serum calcium and phosphorus. Results: We observed that the mean dietary Ca intake was 862.4 mg/d (672.7-1052) for men and 864.2 mg/d (604.5-1123) for women in our population, which is lower than the dietary reference intake for Ca. Moreover, a significant relationship was detected between serum calcium level and dietary intakes of saturated fatty acids, copper, iodine, sucrose, potato, and juices. Of note, we observed a negative association between copper intake, and serum Ca (P˂.01). Also, a significant association was found between serum phosphorus levels and dietary intakes of chicken meat and fresh fruits. Interestingly, we observed an inverse relationship between tea and Ca/P ratio (eg, -r=.098; P=.02). Conclusion: We found that the dietary intake of Ca was not sufficient in our population and was associated with the dietary intake of some macro- and micronutrient, supporting further investigation on clinical impact of this condition on calcium/phosphorus deficiency related diseases. © 2017 Wiley Periodicals, Inc.
